Embodiment 1

[0039] Basic as attached figure 1 Shown: a filter device for a ventilator, including a filter layer 1 and a fixed block 2, the fixed block 2 is U-shaped, and the fixed block 2 is fixed at the air inlet of the fan by bolts.

[0040] The middle part of the fixed block 2 is vertically penetrated with a pipe 3, and the pipe 3 is fixed on the fixed block 2 by bolts; the top of the pipe 3 is provided with a dust-proof mechanism, and the dust-proof mechanism includes a box body 4 fixed on the top of the fixed plate and a The side holes on both sides of the box body 4, the box body 4 is fixed on the fixed plate by bolts, and the bottom of the box body 4 communicates with the pipeline 3; the side holes are welded with a dust-proof net 5, and the dust-proof net 5 is rotatably connected with an anti-dust net. The dust shaft 6 is fixedly connected with negative pressure blades 7 . The top of the box body 4 has an opening, and the opening is threadedly connected with a box cover 37 . The...

Embodiment 2

[0047] Basic as attached figure 2 , attached image 3 , attached Figure 4 And attached Figure 5 As shown: Embodiment 2 is basically the same in structure and implementation as Embodiment 1, the difference is that there is a chamber 11 inside the fixed block 2, and a first rotating shaft 12 and a second rotating shaft 13 are rotatably connected in the chamber 11 , the first rotating shaft 12 and the second rotating shaft 13 are located on the right side of the pipeline 3, the first belt 14 is sleeved between the first rotating shaft 12 and the second rotating shaft 13; the fan blade 15 is fixedly connected to the first rotating shaft 12; A dust-proof plate 8 is provided with a transverse hole communicating with the first air hole, and a transverse block 16 is slidably connected in the transverse hole. The first spring 17 is fixedly connected; the right end of the horizontal block 16 is connected with a steel wire rope 18, and the steel wire rope 18 is wound and fixedly co...

Embodiment 3

[0056] Basic as attached Figure 6 As shown: the structure and implementation method of the third embodiment and the second embodiment are basically the same, the difference is that: the third rotating shaft 38 is rotatably connected in the chamber 11, and the third rotating shaft 38 and the second rotating shaft 13 are socketed There is a third belt 39, the dust sticky layer 40 is bonded on the third belt 39, and the dust sticky layer 40 is a flexible material; the air outlet pipe 20 is arranged towards the third belt 39; an auxiliary hole is opened on the fixed block 2, and the auxiliary hole A sealing cover 41 is threadedly connected.

[0057] The specific implementation process is as follows:

[0058] Dust is driven from the air outlet pipe 20 and acts on the sticky dust layer 40 along with the air flow, so as to realize the collection of dust; after use, the sealing cover 41 is taken off from the auxiliary hole, and the sticky dust layer 40 can be used again for dust co...

Abstract

The invention relates to the technical field of a respiration device and discloses a filtering device for a respirator. The filtering device comprises a filtering layer and further comprises a fixingblock detachably connected with the fan, and the middle of the fixing block vertically penetrates through and is fixedly connected with a pipeline; and a dustproof mechanism for dust prevention of thepipeline is arranged at the top of the fixing block, the filtering layer abuts against the bottom of the pipeline, and the filtering layer is detachably connected with the fixing block. The scheme mainly solves the problem that in a city with more dust at present, a user needs to replace filtering layers repeatedly every day, thereby greatly reducing the use safety.

Description

technical field [0001] The invention relates to the technical field of breathing apparatus. Background technique [0002] The progress of social industrialization and urbanization has made smog more common, as well as the occurrence of social emergency infectious diseases. At this time, it is necessary to take protective measures on the face. The facial protective measures are mainly carried out by wearing masks, etc., through which the particles above PM2.5 At present, the best mask product for isolation is the N95 mask. [0003] The N95 mask can isolate smaller particles, and its filtration efficiency for particles with an aerodynamic diameter of 0.075 μm ± 0.02 μm reaches more than 95%. The aerodynamic diameter of air bacteria and fungal spores varies between 0.7-10 μm, which is A variety of airborne bacteria and fungal spores are also within the protection range of the N95 mask, and the N95 mask fits more closely with the face, and it is not easy to leak air from the pe...
